Pudasjärvi chooses a timber school
The City of Pudasjärvi wanted to invest in a healthy and safe learning environment.
Pudasjärvi chose timber as the building material for its new school campus, which came into use in 2016. The town has had good experiences with wooden buildings, having previously chosen it as the main material for a kindergarten, an assisted living facility, and other buildings.
The main reason for choosing a timber structure is its breathability. Indoor humidity levels and temperatures change and find a natural balance, because woodwalls can store and release moisture and heat. The indoor air in a timber building is also ideal for people with allergies, as a suitable humidity level relieves respiratory problems. And when the air in a room is too dry, the timber structure releases the necessary amount of moisture into the air. In overly humid conditions, on the other hand, the timber absorbs the excess moisture from the indoor atmosphere. This prevents the growth of mold and all the health problems it causes.
A pleasant working environment makes life easy
Wooden buildings also provide comfort, in all seasons. In wintertime timber buildings stay warm, and stay pleasantly cool in the summer. Natural wood creates a pleasant and calming feeling. Timber walls also effectively dampen noise, which is a major bonus in schools.
A pleasing indoor environment makes school life more enjoyable and comfortable for students and staff alike, and in the process promotes success in study and other school activities.
An ecological and safe alternative
Modern industrially processed timber is long-lasting and ecological, but at the same time is a highly affordable construction material with impressive technical properties. A timber building is energy-efficient and economical to maintain.
A solid wood building contains a large amount of sustainably produced timber, making it an effective carbon sink. A wooden building binds almost double its weight in carbon dioxide from the atmosphere, which considerably reduces the CO2 content of indoor air.
Timber is a renewable raw material, and is the only energy-positive construction material: burning the by-products of timber processing provides more energy than is consumed in constructing the building.
When it comes to fire safety, no risks were taken at Pudasjärvi. The main kitchen of the school campus and the technical workshops were located in the part of the building made from concrete, where the school's civil defence shelter is also situated.
The world's largest wooden school
The timber campus in Pudasjärvi is the largest school building in the world to be made of wood. Lemminkäinen planned and implemented the construction of the school campus and, in accordance with the life cycle model, is responsible for the upkeep, maintenance, user services and maintenance renovations of the school for 25 years. The pine timber was supplied by Kontiotuote Oy, a local manufacturer, and the timber was sourced from within an 80-kilometre radius of the construction site.
